HEAT EXCHANGER FOR LIQUEFIED PETROLEUM GAS

摘要

PROBLEM TO BE SOLVED: To provide a heat exchanger capable of preventing stickiness of a heavy component while making the best of advantages of conventional coiled pipe or saving type heat exchangers by one apparatus. SOLUTION: This heat exchanger for a liquefied petroleum gas comprises a coiled pipe 1 arranged in the interior of a warm water tank 3 to be heated by a heater and a chamber column 2 connected to an outlet of the coiled pipe. A heat exchange part of the coiled pipe has such a heat transfer area as not to completely evaporate an LPG liquid, and an unevaporated LPG liquid is evaporated in the chamber column 2. Or, the objective heat exchanger for a liquefied petroleum gas comprises a coiled pipe and a chamber column connected to an outlet of the coiled pipe. A part of an LPG liquid introduced to the coiled pipe is evaporated there and an unevaporated LPG liquid is evaporated in the chamber column.
